A person who has just given you their email address is as interested in your store as they will ever be. They have a reason for being there, a minute ago they were thinking about your products and they are expecting to hear from you. A welcome email series makes use of that moment, and in most stores it is among the best-performing automations, because the audience is warm and the message is welcome. It is also, surprisingly often, an afterthought: a single automatic email with a discount code, followed by silence.
This guide describes a five-email welcome series that fits most online stores. It explains the purpose of each email, gives sample wording, covers the discount question honestly, shows how to adapt the series to different kinds of subscribers and sets out the numbers to track. It follows on from the structure in Klaviyo flows best practices, where the welcome flow is the first of five core flows, and it complements the recovery messages in abandoned checkout email examples.
What a welcome series should achieve
- Deliver what was promised. If the signup offered a guide, a code or early access, it arrives at once.
- Introduce the brand. Who you are, what you stand for and why a stranger should trust you.
- Show the products that matter. Bestsellers, categories and the best way to start.
- Remove doubts. Delivery, returns, sizing and quality, answered before they are asked.
- Invite the first order. Without pressure, and with a reason to act.
- Set expectations. How often you will write and what you will send, so the list stays healthy.
The five-email plan
| Timing | Purpose | One thing it must do | |
|---|---|---|---|
| 1. Welcome | Immediately | Deliver the promise and say hello | Keep the promise in the first screen |
| 2. Our story and proof | Day 2 | Build trust with a short story and real evidence | Show one credible proof point |
| 3. Start here | Day 4 | Guide to bestsellers or the right starting point | Offer a clear path, not a catalogue |
| 4. Questions answered | Day 7 | Handle the common objections | Answer the top three questions |
| 5. Ready when you are | Day 10 | A gentle invitation to order | Give a reason to act, honestly |
Email 1: the welcome (immediately)
Send it within a minute of signup. Say thank you, deliver the offer or content the form promised and tell the reader what to expect. Keep the design light and the message short. If a discount was promised, put the code at the top, so that it does not feel like a trick.
Email 2: our story and proof (day 2)
People buy from brands they believe in. Tell the short version of how and why the store started, in the first person where possible, and add one piece of real proof: a review, a number of customers served, a press mention or a photo of the workshop. Resist a long history; two paragraphs are enough.
Email 3: start here (day 4)
A new subscriber often does not know where to begin. Offer a guided choice: our three bestsellers and who each suits, or a short quiz link, or a set of categories described in a sentence each. Show the products with pictures and prices, and make one clear button for the most common starting point.
Email 4: questions answered (day 7)
By now the person has seen the brand and the products but has not bought. Something is holding them back, and it is usually one of a handful of things: delivery cost and time, returns, sizing or fit, quality, payment security. Answer the top three from your own support inbox, in plain words, with links to the policy pages. This email often converts people who needed reassurance rather than a push.
Email 5: ready when you are (day 10)
The last message of the series is a calm invitation. Remind the reader of what you offer, mention anything genuinely time-limited and give a clear route to order. If a discount is part of your plan, this is the place for it, set out in the discount section below. After this email, the person moves to your regular newsletter or campaigns.
The discount question
Many stores promise a discount for joining. It grows the list, and it also attracts people who join only for the code and may never buy at full price. The right choice depends on your margins, your brand and your list goals. Whatever you decide, decide deliberately, not by default.
| Approach | Strength | Weakness | Fits |
|---|---|---|---|
| Discount for joining, in email 1 | Grows the list quickly and gives a clear reason to sign up | Trains code hunters and lowers margin on orders that might have been full price | High-margin stores competing on price |
| Discount held to email 4 or 5 | Gives full-price buyers time to order first | Sign-up rates may be lower | Stores with healthy margins and strong brands |
| Free shipping instead of a percentage | Removes the commonest barrier and protects the headline price | Shipping costs are real | Stores where shipping cost causes abandonment |
| Gift or content instead of a discount | Attracts people who value the brand | Smaller immediate lift | Premium and craft brands |
| Tiered by signup source | Matches the offer to the reason for joining | More to build and test | Stores with several signup routes |
Whatever you choose, use a unique, single-use code where your platform allows it, so that a code cannot be shared widely, and set a minimum order value that protects your margin. A guard rule that checks each cart before applying an incentive is the same idea we describe in the abandoned cart context, and it applies here too.
Segment the series by how they joined
A one-size series wastes the most valuable information you have: why the person signed up. Someone who joined from a pop-up on a blog post has different expectations from someone who left their email at the end of a quiz, and both differ from a customer who has already bought. Create separate entry paths, even if they share some emails.
| Signup source | What they expect | Adjust the series by |
|---|---|---|
| Pop-up on the site | The offer on the pop-up | Deliver it at once; use the standard five emails |
| Content or guide download | The guide, then related help | Lead with the guide and related products; slower sales language |
| Quiz result | Personal recommendations | Use the quiz answers to choose products in email 3 |
| Checkout or account creation | Order updates | Skip the welcome-to-buy emails; send a customer onboarding series instead |
| Giveaway or event | A prize or news | Be careful: many are low-intent; keep the series light and clean the list quickly |
| Wholesale or B2B inquiry | Terms and contact | Route to a person, not a consumer series |
Writing tips that apply to every email
- One idea and one button per email. A welcome is not the place for five calls to action.
- Write in the first person plural or singular as the brand speaks, and sign with a real name where it fits.
- Use plain subject lines that say what is inside, and test two versions of the first.
- Make it mobile first. Most welcome emails are read on a phone.
- Invite replies. A real reply address gives you honest feedback and improves deliverability.
- Authenticate your domain so that the first email reaches the inbox; the first email sets your reputation with a new subscriber.
Consent and compliance
A welcome series is marketing, so it needs a lawful basis. Collect consent clearly at signup, say what people are signing up for and honour unsubscribes immediately. For texts, consent rules are stricter in many countries. Keep a record of when and how each person agreed. Our compliance basics page points to the official guidance for each region, and nothing here is legal advice.
What to measure
| Measure | What it shows | Watch for |
|---|---|---|
| Revenue per recipient | Money earned per subscriber who entered the series | Compare with a holdout of new subscribers who receive nothing |
| First-order rate within 30 days | Share who buy | Differences by signup source |
| Unsubscribe and complaint rate | Whether the series feels welcome | A spike after a particular email |
| Click rate by email | Which emails interest people | Compare the story and start-here emails |
| Time to first order | How quickly it converts | A late peak suggests adding a day-14 message |
| Discount usage and margin | Cost of the incentive | Orders that used the code and their margin |
A worked example
Imagine a store with 4,000 new subscribers a month. Without a series, about two percent make a first purchase within thirty days from ordinary browsing. With the five-email series, suppose six percent do. That is 160 extra first orders a month. At an average order of sixty dollars and a thirty-five percent margin, the extra contribution is about $3,360 a month. If a discount costs ten percent on those orders, subtract roughly $960, leaving about $2,400. The numbers will differ for your store, and some of the lift would have happened anyway, so the holdout comparison is how you find the truth. But even cautious assumptions show why the welcome series is usually the first flow worth building, and the last one worth neglecting.
If you want the series written, built and tested on your platform, with segmentation by signup source and a margin guard for the incentive, see our email and SMS marketing flows service. For the segmentation itself, customer segmentation builds the audiences, and the post-purchase email flow takes over when the subscriber becomes a customer.
